I'm getting interested in the Moller/Arkhangelsk lines from the new Kaufman book.
1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 0-0 Bc5!? 6 c3 (6 d3 transposes to 5 d3 systems, 6 Nxe5 is okay for Black and not too common, and 6 Bxc6 is an Anti-Berlin type system [with castling maybe a little early?]. 6...b5 (instead of the trendy 6...0-0) and now:
A) 7 Bc2 d5 8 d4 (8 exd5 Qxd5 is fine for Black, Kaufman gives an interesting piece of analysis after 8 a4!? dxe4 9 axb5 Bg4!? which I haven't checked yet) 8...dxe4 9 Nxe5 (alternatives seem less dangerous) and the resulting ending [Stevic-Brkic, Porzega 2018] is super drawn objectively; I let Stockfish and Komodo have like an eighteen game engine match and everything was drawn. In human chess both players can still win - maybe Black has to be a bit more careful since he's an exchange down?
B) 7 Bb3 d6:
B1) 8 a4 Bb7 9 d3 (9 d4 transposes below) 9...h6 10 Nh4! is not mentioned; I posted some analysis in the other thread, I think 10...Bc8! is the only fully acceptable move for Black.
B2) 8 d4 Bb6 9 a4 (alternatives to this are not discussed, but it's known from the Yurtaev Variation that these aren't too dangerous - I like a setup with ...h6, ...Re8 and ...Bd7, but ...Bb7 is possible too obviously, and consistent) 9...Bb7 and now 10 Re1 (! - Kaufman; 10 Bg5 h6 11 Bxf6 Qxf6 12 Bd5 is briefly but nicely covered, Black has a clear plan to equalize) 10...0-0 (10...h6?! 11 Be3 and eventually d4-d5) 11 Bg5 h6 12 Bh4 exd4 (I think this is slightly more accurate than 12...g5 immediately) 13 cxd4 g5 14 Nxg5! (14 Bg3 Re8 is okay) 14...hxg5 15 Bxg5 is extremely complicated but Black seems to be able to walk a narrow path to a draw. Kaufman therefore says that this variation is probably best for correspondence, but White also has to know what he's doing, and it's not like he's risking nothing. In engine tests, White won some games by deviating from Pichot-Lodici, Manavgat 2018 with 22 Re4!?, and eventually winning some Bishop and pawns vs. Rook ending after following Kaufman's analysis. IDeA come up with an idea for Black to improve that as far as I can tell should draw. I have no idea what's going on here.
Any thoughts?
